Bed bugs are parasitic insects that prefer to feed on human blood. The common bed bug, Cimex lectularius, is the most famous species of the Cimicidae family. The name of the “bed bug” is derived from the insect’s preferred habitat of being in the vicinity of beds and other areas where people sleep. Bed bugs are mainly active at night but are not exclusively nocturnal and are capable of feeding on their host without being noticed. Bed bug bites may cause a number of adverse health effects, including skin rashes, psychological effects and allergic symptoms.
